Ring Group Call Confirm Issue

I am running the current distro of 10.13.66, when we setup a ring group and assign an outside number to confirm calls, when the person being called presses #1 it will not connect the call, but will say the call is no longer available every time.

I was able to get it to work with queues but not with ring groups. Any ideas? Thanks
